> Patch 12651 (reverted by patch 12666) reintroduced portable native sync for the gtk peer AWT threading. It removed a syswrap hijack of 2 pthread calls which prevented deadlock in GTk code. This introduced an inefficiency in the way scheduled AWT threads, but this was better than a deadlock. We should re-apply 12651 but we can only do this if Classpath is rebuilt on the test infastructure machines with --enable-portable-native-sync on their configure scripts. More generally the test infrastructure machines should rebuild Classpath.
